Strength Stat Increased Bug

Hello So suddenly a character's (Dwarf King) strength stat increased to 44262615, and it appears in blue as if it were a stat boost, I tried changing it in the attributes tab but it increases again to that big number after I try putting any other number in the stat to update the abilities, saves, etc. It happens in Chrome, Firefox and Edge. No extensions. Windows 10 Campaign DND YO Character Trystan Bronzebeard

Hi Ale M.,  Most likely a piece of equipment is causing it. Please disable all equipment on the sheet one at a time until you find out which one is doing it. Delete that piece of equipment and re-add it.  Note: please report which piece of equipment caused it. I am curious to find out. 

YES, It was the Giant Slayer Battleaxe from the compedium (PB14) Thanks! Gauss said: Hi Ale M.,  Most likely a piece of equipment is causing it.

Thanks, I don't see anything wrong with it normally, but sometimes the entry (mods section) for a piece of equipment gets corrupted.

Messing around with the item I discovered it is the word Strength in the mods section of the item "and must succeed on a DC 15 Strength saving throw" , I replaced it with STR and it turns back to normal lol
